Their larvae feed on stored food and contaminate it with their feces. Their webs, which clump flour, semolina, etc., are conspicuous.
The dried fruit moth is a moth and belongs to the same family as the European corn borer. It was introduced into Central Europe in the 19th century and, due to its broad food spectrum - it eats dried fruit, nuts, chocolate, cocoa, pasta, spices, cereals of all kinds and numerous other plant products - its robustness and resistance to cold has now made it a fixture in many storage and manufacturing facilities of food-producing companies as well as in households.
Despite its resistance to cold, the dried fruit moth benefits from rising temperatures as a result of climate change: more generations are formed each year. This increases the pest pressure in storage facilities if they are not air-conditioned.
